Percent Lost vs Pounds/Kilos: The Fair Way to Compare

“Brenda lost 10 kg and I lost 5 kg.” That sounds lopsided—until you realize Brenda started 40 kg heavier. Percent lost tells the fair story.

Why percent beats raw kg/lb

• Normalizes for starting point: 5% is meaningful whether you started at 70 kg or 120 kg.
• Lines up with health milestones: Many clinical goals use 5% and 10% benchmarks.
• Cleaner cohort comparisons: Percent lets you compare apples to apples.

How we show it

• Your dashboard highlights % from baseline.
• Cohort charts use percent so your line sits next to “people like you” fairly.
• We still show kg/lb in your logs—because both views help.

A quick example

• Person A: 120 kg → 114 kg (−6 kg = 5%)
• Person B: 80 kg → 76 kg (−4 kg = 5%)
  Same 5% means similar progress.
